Atlasman...if you really believe all that "STUFF" there's really no need of adding my flame to the fire. I guess the simplest way out is to just remind you that we've been trying to eliminate fletching and arrow contact with rest, risers etc forever.... and always will. The slightest of form errors and grip changes will effect the arrows if there is contact up front .... or in the middle.... or in the back on any arrow. If a guys form is PERFECT he doesn't have much to worry about. THere aren't many like that. With the wierd shooting positions we find in a tree stand at times these errors are multiplied.You may not beable to relate group sizes to different rest, but hey...like you said, everyone isn't the same and doesn't have the same standards. An inch error at 20 yards is a whole lot bigger at 45. Most people are limited in shot distance not because of ethics or deer movement, but because of group size and form problems. Personnally, if I can get the best equipment that gives me the most room for flaws and allows me to still hit what I aim at, I think I just picked up a few yards. The WB is a so so archers crutch as far as I'm concerned. It's good enough for him, but not for me. The also make more noise and tear the heck out of fletchings. Who needs that.
